Toxic pollutants entering into aquatic environment exert their effect through altering redox cycling in fish. The antioxidant defence as well as oxidative damage is a common effect in fish exposed to xenobiotics in their water body. Brain requires high and constant oxygen supply to meet its energy needs and generates more free radicals per gram of tissue than does any other organ in the body. T...

The precise detection of genotoxic effects induced by environmental contaminants is an essential part of any genetic toxicology screening programme. Fish, however, provides a sensitive monitor for environmental genotoxicity in aquatic environment. Mugil cephalus genome has now been employed in this study for detection of clastogenic and cellular lesions induced by aquatic contaminants in Abu-Qi...

Mining of the world's second-largest nickel deposits in the area of Sudbury, Ontario, Canada, has caused acidification and metal saturation of some catchments. We conducted artificial stream studies in the years 2001 and 2002 to assess the effects of treated metal mine effluents (MMEs) from three different mining operations discharging to Junction Creek, Sudbury, on two fish species, creek chub...

Fish collected after a mass mortality at an artificial lake in south-east Queensland, Australia, were examined for the presence of nodularin as the lake had earlier been affected by a Nodularia bloom. Methanol extracts of muscle, liver, peritoneal and stomach contents were analysed by HPLC and tandem mass spectrometry; histological examination was conducted on livers from captured mullet. Liver...

Infection with the liver fluke, Opisthorchis felineus, caused by consumption of infected raw or undercooked cyprinid fish is common in humans and carnivores middle Ob River basin (Tomsk region, Russia) can lead to diseases humans. The goal this study was status infection O. felineus metacercariae order assess role human population basin. Of 14 Cyprinidae species recorded basin, we examined 6 fo...

Pneumonia is one of the prime causes of morbidity and mortality in children under five years of age. Objectives: To determine the frequency of pneumonia, to identify the causative organisms and the factors associated with death in children under 5 years of age. Methods: A prospective cohort study was performed in children 1 to 59 months hospitalized for pneumonia between January and June 2016 i...
